Redesign of SoundNode

SoundNode ( [login to view URL] ) is a free open source web radio. And we'd like to have this project modified for our needs. Project info: - We need a radio player which will not play using streams, the player must to download an encrypted MP3 file, save it on the File System, and play it without the need of internet connection ( once downloaded ofcourse ). - Once the system detects internet connection, it must to sync all playlists/songs as long as validate whether the account is expired or not. - The playlists concept will be kept. And the playlists must also be saved on the file system once downloaded, in order to be used without internet connection. - There might be commercial spots between the musics on the playlist. And the user must to choose which spot is going to played or not, as long as the number of musics between a commercial spot be played. - Dual channel needed to play 2 songs at same time. This will be used when the current song being played, and there are 5 secs missing until the next song, the next song must to start being played, and it's volume must to be increased slowly from 0 to 100%, giving a fade effect to the end user. - The project must to have a login system which will expire only when the account expire ( if expire ). All the backend will be provided, so the coder must to work only on the front end side. The backend will be coded along with the front end development. Tecnologies envolved: - Node.js - Electron - Angular.js
